[Edited January 2 2019 -- to remove or replace dead visual-links]
Long ago Jonathan and I got some good traction out of a tangle of issues related to Global Warming slash Climate Change. I think we are slated to renew or refresh our earlier exchanges. I am going to poke in links to some he-said/he-saids from a few different threads at different times. One feature of the updated software is an automated 'sampling' of a link posted raw. See below.
So this blog entry will be kind of administrative-technical while being built and edited. I haven't figured out if Jonathan and I should impose some 'rules' going in, so your comment may be subject to arbitrary deletion before the field is ready for play. Fan notes included.
Plug my How To Get Where I Got book of books, Spencer Weart's The Discovery of Global Warming. Insert link to Amazon, Library link, and to the intro chapter of Weart's companion website to the book. Make sure you include a link to Ellen's mention of a book review.
Bob Kolker's June 3 comment is a good hinge. What do we (J and I) think we know about the mechanism Bob sketches? What can we 'stipulate' or what can we agree on, for the sake of argument?

CO2 does slow down the radiation of energy in the infra-red bandwith. The question is to what degree given that there are other systems that tend to diffuse and disperse heat (such as the Pacific Decadal Oscillation and El Nino, along with convection and the Coriolis Effect that moves warm are to the polar regions). The scientific fact is that CO2 tends to absorb radiated energy in the infra red range. That is NOT fabricated. That is a matter of experimental fact.
The issue is to what extent is the CO2 load of the atmosphere is slowing down heat radiation into space, when such absorbing or radiation occurs along with other heat dispersing processes.
No denies that putting a blanket on, when it is cold slows down the rate at which one's body radiates heat. Air is a poor heat conductor and the blanket traps air. Also the blanket is warmed and radiates half its heat back to the source. This produces a net slowing down of heat loss. Heat loss still occurs (Second Law of Thermodynamics in operation) but the rate of loss is affected.
Tyndol and Arhenius established the heat absorbing properties of CO2 in the late 19 th and early 20 th century. Subsequent work has show the absorbtion to be the case and has measured it even more accurately than Tyndol and Arhenius.
